WarpVortexMask

In the S_WarpsMask Plugin.

Twists the source clip into a vortex, about a given Center location. Use the Vortex Start parameter to adjust the amount of vortexing, and use Angle Offset to also apply a normal rotation. Vortex Speed can be used to automatically animate the amount of vortexing.

Inputs:

Source:  The input clip to be warped.

Mask:  The amplitude of warping is scaled by the values of this input clip. Gray values internally scale the warping amplitude rather than simply cross-fading between the effect and the original source to allow more continuous results at the Mask edges and more detailed control over the warping amounts. Only the red channel of this input is used. This input can optionally be blurred or inverted using the Blur Mask or Invert Mask parameters.
        

Parameters:

Vortex Start:   Default: 36,  Range: any.
The amount of vortex rotation, in approximate counter-clockwise degrees at the edge of the frame.

Vortex Speed:   Default: 0,  Range: any.
The speed of the vortex rotation, in approximate degrees per second at the edge of the frame. If non-zero, the vortexing is automatically animated at this rate.

Inner Radius:   Default: 0.04,  Range: 0 or greater.
The radius from the center at which the vortexing is phased in. This can be used to reduce excessive distortion and aliasing at the very center of the vortex.

Angle Offset:   Default: 0,  Range: any.
If non-zero, a rotation is combined with the vortex. Make negative to rotate the inner and outer regions in opposite directions.

Center:   X & Y,   Default: [0 0],  Range: any.
The center of the vortex, in screen coordinates relative to the center of the frame. This parameter can be adjusted using the Center Widget.

Z Dist:   Default: 1,  Range: any.
Scales the 'distance' of the image. Values greater than 1.0 move it farther away and make it smaller. Values less then 1.0 move the image closer and enlarge it.

Filter:   Check-box,  Default: on.
If enabled, the image is adaptively filtered when it is resampled. This gives a better quality result when parts of the image are warped smaller.

Wrap:   X & Y,  Popup menu,  Default: [REFLECT REFLECT].
Determines the method for accessing outside the borders of the source image.
NO:  gives black beyond the borders.
TILE:  repeats a copy of the image.
REFLECT:  repeats a mirrored copy. Edges are often less visible with this method.

Blur Mask:   Default: 0,  Range: 0 or greater,  Shared.
Blurs the Mask input by this amount before using. This can provide a smoother transition between the masked and unmasked areas.

Invert Mask:   Check-box,  Default: off,  Shared.
If enabled, inverts the mask input so the effect is applied to areas where the Mask is black instead of white.
